Oxytocin at a glance
Oxytocin is a nine-amino-acid hormone made in the hypothalamus and released by the posterior pituitary. It controls uterine contraction and milk release, and acts in the brain on social behavior.
Synthetic oxytocin is an approved obstetric drug.
How Oxytocin acts in the lab
Oxytocin acts on the oxytocin receptor, a G-protein coupled receptor found in the uterus, breast tissue and many brain regions.
In the body it triggers contractions and milk letdown. In the brain it’s involved in social recognition, bonding and stress responses, which is what most current research is about.

Oxytocin 10mg reconstitution and concentration
Here’s the math for 10mg of peptide:
- 1ml of bacteriostatic water gives 10mg/ml
- 2ml of bacteriostatic water gives 5mg/ml
- 3ml of bacteriostatic water gives 3.33mg/ml
Pick the volume that keeps your own calculations simple, then write the concentration and the mixing date on the label.
Bacteriostatic water is the standard choice. Add it slowly so it runs down the side of the vial, then swirl or roll until everything dissolves. Shaking can damage the peptide, so skip it.
How to store Oxytocin 10mg
The dry powder keeps best cold: 2 to 8°C in the fridge, or -20°C for long-term storage. After reconstitution, store it in the fridge and finish it within roughly four weeks.
